Alexander KuznetsovIn this paper, we addressed the flow patterns over a light boxplane scale model to explain the previously discovered disagreement between its predicted and experimental aerodynamic characteristics. By tuft flow and CFD visualization, we explored the causes yielding a large zero lift pitching moment coefficient, lateral divergence, difference in fore and aft elevator lift, and poor high lift performance of the aircraft. The investigation revealed that the discrepancy in the pitching moment coefficient and lateral stability derivatives can be attributed to insufficient accuracy of the used predictive methods. The difference in fore and aft elevator lift and poor high lift performance of the aircraft may occur due to the low local Reynolds number, which causes the early flow separation over the elevators and flaperons when deflected downward at angles exceeding 10°. Additionally, some airframe changes are suggested to alleviate the lateral divergence of the model.

Kirill AlexandrovThe paper presents specifications for the Long-Endurance Mars Exploration Flying Vehicle (LEMFEV), which will be used as future design input data. The specifications are based on the analysis of previous Mars missions and scientific data collected by the operating Martian probes. The design specifications include the requirements related to the airplane’s delivery to the Martian surface; the requirements related to the Martian conditions (atmosphere and climate); and the requirements related to the scientific payload parameters and the mission flight profile.

Manoranjan SinhaThis study aimed to explore the directional stability issues of a previously studied light box-wing aircraft model with a pusher propeller engine in the fuselage aft section. Earlier configurations have included the use of fuselage together with a lifting system consisting of two wings joined together at their wingtips with vertical stabilizers. However, these side vertical surfaces failed to provide the aircraft with sufficient directional stability, thus prompting the quest in this study for novel solutions that would exclude the need for a fuselage extension and a typical fin. Solutions included the use of a ducted propeller and few configurations of small “fishtail” vertical fins, which formed part of the aft fuselage itself and coupled with vortex generators on the fuselage surface to improve their interference and heal flow separation at the fuselage aft cone. The results of wind tunnel testing were supported with CFD simulations to explain the flow behavior of each of the studied solutions. Tuft visualization and computed flow patterns allowed identification of the sources of the observed low efficiency in terms of directional stability of the fishtail against a simple idle duct without a propeller. A final configuration with a duct and a modified version of the fuselage fins was achieved that provides enough yaw stability margins for a safe flight.

About Me
Elena Karpovich is an aircraft engineer and an assistant professor with a Ph.D. in aeronautical engineering. Elena specializes in aircraft aerodynamic design.
Since 2012, Elena has been working as a design engineer for the preliminary design department of Irkut Corporation, Moscow, Russia. In addition, she has given lectures and introductory short-term courses to interns and high-school visitors to the corporation's Engineering Center.
In 2021–2023, Elena developed three courses for Moscow Aviation Institute (MAI) Ph.D. students, including a course on academic writing and peer reviewing. Also, in 2022, she created an online course, Introduction to Aircraft Aerodynamics, which one can find here: https://en.mai.ru/education/online/aerodynamic_design/.
As an assistant professor, Elena also delivers a scientific seminar on aircraft engineering to MAI Master's degree international students, serves as a technical translator, and has some experience in chairing conference sessions.
Elena holds honors degrees in aircraft design, aerodynamics, and Greek philology. In fulfilment of her life-long learning approach, she has benefited from numerous supplementary courses, including the Peer Review and Mentoring in Peer Review courses by the Publons Academy (Web of Science Academy), the Psychology of Public Speaking, and the Pedagogy in Higher Education courses.
During her scientific career, Elena has twice been awarded a certificate for the best conference presentation.
